Nonobstructive Coronary Artery Disease Increases risk of Death

Nonobstructive coronary artery disease (CAD) can increase risk of death or heart attack significantly, a new study reported. The researchers found that the risk spiked within one-year post diagnosis.

According to the press release, nonobstructive CAD is characterized by "atherosclerotic plaque that would not be expected to obstruct blood flow or result in anginal symptoms." However, there have been studies that questioned the potential health dangers of nonobstructive CAD.
